If it's really only a web server, then you probably don't
need the USB ports.  In that case you should remove ohci
and ehci from your kernel.  The USB interrupt handler is
quite heavy-weight, so it can have a noticeable impact if
the interrupt is shared with other devices.

(On the statement print "42 monkeys" + "1 snake":)  By the way,
both perl and Python get this wrong.  Perl gives 43 and Python
gives "42 monkeys1 snake", when the answer is clearly "41 monkeys
and 1 fat snake".        -- Jim Fulton
